General Description
The CH7009 is a Display controller device which accepts a
digital graphics input signal, and encodes and transmits
data through a DVI TMDS
TM
link (DFP can also be
supported) or TV output (analog composite, s-video or
RGB). The device accepts data over one 12-bit wide
variable voltage data port which supports five different
data formats including RGB and YCrCb.
The DVI processor includes a low jitter PLL for generation
of the high frequency serialize clock, and all circuitry
required to encode, serialize and transmit data. The
CH7009 comes in versions able to drive a DVI display at a
pixel rate of up to 165MHz, supporting UXGA resolution
displays. No scaling of input data is performed on the data
output to the DVI device.
The TV-Out processor will perform non-interlace to
interlace conversion with scaling and flicker filters, and
encode the data into any of the NTSC or PAL video
standards. The scaling and flicker filter is adaptive and
programmable to enable superior text display. Eight
graphics resolutions are supported up to 1024 by 768 with
full vertical and horizontal underscan capability in all
modes. A high accuracy low jitter phase locked loop is
integrated to create outstanding video quality. Support is
provided for Macrovision
TM
and RGB bypass mode which
enables driving a VGA CRT with the input data.
